Question

sound is a type of energy. a medium is needed to carry sound.

sound cannot move unless there are enough particles. the particles in the medium pass the

vibrations along.

sound can travel through solids, liquids, and gas mediums. the speed that sound travels

depends on the medium it is traveling through. for example, sound travels fastest

through steel, then it travels through water, and sound travels slower through air than it

does through water.

where would sound not be able to travel?

through the ocean

through the air

through outer space

through the ground

Explanation:

Sound requires a medium (solid, liquid, gas) to travel. Outer space is a vacuum with no particles to carry sound waves. The ocean (liquid), air (gas), and ground (solid) are all media that can transmit sound.

Answer:

through outer space
